To all whom it mayrconoern:

Be-it known that I,"HENRY CLAY WAD a citizen of the United States, and a reel! may be employed. Fig. 4; is a plan view of the burner. Fig. 5 is a sectional plan view through the burner, taken on the line dent of New York, county and.Statef of v -New York, 'have inventedoertain new and which a fluid, as kerosene oil, may be caused to pass to the burner and there vaporize and the vaporized fluid caused to mix properly with air in such a way that thesa'id mixture will produce an efiective blue orheat flame, at ,the same time prov1de a burner which will remain free from carbon or other objectionable .matter which is likely to reduce the-efiiciency of the burner and cause the same to smokefthus overcomi g many of the objections incident to oil stoves'and burners heretofore proposed for vaporizing and burning keroseneoil.

"Another object of the invention'is to provide. a burner which is simple in construe tion, which may be readily made and assembled, and which may be employed in various connections.

A further object of the invention is to provide simple means whereby the kerosene oil for the initial heater and the burner may be supplied from'the same source.

. A still further object of the invention is to provide a burner which is particularly adapted to produce a blue heat flame, and

Fig. 10 is a sectional view, taken on the line X-X of Fig. 9 Fig. 11 is a sectional view, taken on the line XI XI of Fig. 9; and Fig. 12 shows how two initial heating devices may be employed .so as to heat the burner from opposite sides to initially vaporize the oil While- 1 show a stove and" a burner of I one" form and in which the source of supply is arranged in a particular way, it will be understood that the burner may be used for any purpose and in any connection, and

parts".dispensed with, if desired, without: vdeparti'ng'from the spirit and scope of'my that some of the parts may be difiierently arranged or constructed, or some of the invention, as defined and 'set forth in the appended claims. I

' The frame or body of the stove 10 or other support may be of any suitable construction and said body may have means, as the plates 11, on which receptacles may be placed to be heated, and under the stove or in any to provide means whereby the oil may be positively driven to the burner in such a way as toavoid all likelihood of-accident, and which means may be easily controlled. .With. these and other objects in view,

other suitable location may be arranged a tank or reservoir 12 in which the kerosene oil or fluid to be vaporized is located. This reservoir may be held to the lower portion of the stove by straps 13, or otherwise, and at one side of the stove may be arranged a pipe or connection 14, the outer end of which'may be closed by a cap, as 16. The

a cap 16 may be provided witha cook or valve the invention will be hereinafter more pa-rticularly described with. ref rence to the accompanyingdrawings, which form' a part of this specif cation, and will then be pointed out in. the claims scriptions 1n the drawings, Figurel IS a front elevation, partly, in section, of one form 'of' means embodying my. invention. Fig. 2 is a side elevation. Fig.3 is anenlarged vertical section of .one 'form of burner which at the end of the del7,"and when the cap is removed, the cock 17 is also removed therewith and will permit the tank to be filled through said pipe or connection 14, the purpose of the cock being to, permit air within the tank or reser voir to escape therefrom. The pipe 14. has its inner end arranged above the normal oil level, and connected to said pipe is a pipe 18 which leads to an air pump 19. This pump 19 mayv be ofthe usual hand operated kind and may be secured to the A pipe 25 is secured to the tank so that its end 26 extends inward below the level of the oil, and at a convenient point above the tank is located a valve 27 of any suitable kind by which the oil in the pipe 26 may be readily cut off, it being understood that" the oil will be forced through the pipeg26 by means of the air pressure within thetank above the oil. At the upper portion of the pipe'25 is a burner 28. As shown in the drawings, there are two burners and connections therefor provided for heating purposes,"and a burner for lighting purposes to be referred to hereinafter, though a "single burner may be employed or the number of burners may be varied according to the use to which the same is put, and the size may vary according to the body to be heated or the use to which the burner is applied.

The burner 28 may have a casing or supporting member 29 having a pipe or tubular portion 30 which may be secured by a coupling, as 31, to the upper portion of the pipe 25, and this casing has a stem portion or member, as 32, provided with a projecting threaded boss 33 to which one end of the tube or'member 34 is secured. This member 34 is threaded at its upper end and engaging said threads is a boss or base portion 35 of the burner proper 36. A part or extension 37 projects from the boss'33 and said extension is somewhat smaller in crosssection than the interior of the tube 34 so as to provide a space or chamber'38 around said extension, and in this space is a wire gauze 39 or other heat conducting means through which the oil must pass before it reaches the burner, and which gauze serves to break up the oil into fine particles. The

stem portion 29 is arranged in parallel rela tion to the part 30 of the casing and is connected therewith by the tubular portion 40. A passage 41 extends through the connection 40 and this passage communicates with the tubular part 30 and the passage 42 in the stem member 29, and through which the oil passes to the chamber 38 around and about the gauze 39. A cap 43 is held to the outer end of the tube 34 and in this ca are a plurality of openings, as 44, throng which thevaporized oil, passes, and above the,cap 43 is a plug 45 having a threaded outer surface engagmg a threaded opening ,which t e vapor and air .escape to in the part 35 and having means, as recesses 46, by which the plug may be rotated, thus serving to hold the cap 43 in place. An opening 47 of preferably very small cross-section is formed substantially centrally of the plug or member 45 and under said opening is a chamber, as 48, above the end of the extension 37 through which the vapor may pass to the opening 47, and in alinement with said opening is a relatively small pin or device 49 which is arranged on the outer end of the longitudinally-movable stem or rod 50 so. that by the movement of said rod, the pin or device 49 may be caused to pass through the opening 47 thereby serving to clean the same and to keep the opening free of any carbon or any matter that mig t collect to close said opening, the said pin serving also in a measure to act as a valve to prevent the vapor passing through said small opening. The stem or rod 50 has one-end threaded, as at 51, and on said threaded end is a finger lmob or handle 52 by which the said rod may be rotated. The threaded end 51 engages a threaded aperture 53 in a stufiing box 54, and this stufiing box 54 has a threaded portion, as 55, to engage a threaded recess, as 56, in which may be packing, as 57, by which leakage past the rod or device 50 is prevented. By this means a very effective supply for the oil is provided and when vaporized, as will be hereinafter described, the said vapor may be properly controlled and at the same time the opening through the plug 45 is prevented from becoming obstructed by any objectionable material.

The burner proper has a cup-shaped member 58 formed integral with the boss or part 35, and in said member 58 are a plurality of openings 59 through which air may pass so as to commingle with the vapor as it passes through the small opening 47. The upper portion of the member 58 is recessed to form a shoulder 60 and resting upon this shoulder is a cap or member 61. This cap or member has a threaded opening, and this threaded opening is engaged by the threaded end of a tapered tubular stem or part 62, the upper portion of. which is contracted and provided with a surrounding flange, as 63, forming an inverted cup-like device or member, the downwardly-extending wall of which rests upon the upper surface of the cap 61, there being a flange or bead, as 64, serving to guide and hold the device in position. An inverted cup-shaped member or device is located above and concentric with the-'cup-like member 63 and is somewhat larger than the same so as to provide amixing chamber 66 for the air and vapor, and said cup-like member has a downwardly-extending wall or flange 67 provided with a lurality of openings 68'throug)h lighted. The flange 67 is' separated somewhat from the flange or wall 63 and said cup-shaped device is centered by means of a flange 69 on the head or cap 61, and adjacent' to the flange 67 is an outwardly flared flange or part 70, substantially bellshaped, formed as a part of the cup-shaped member 58, against which the vapor strikes and which causes the flame to spread upwardly and outwardly substantially belllike. The vapor and air are thus properly and thoroughly mixed and the parts are so constructed that when once heated, the heat will be conveyed back to the part where the oil enters the space 38 and will effectively vaporize the same so that a perfect heat flame is produced free of carbon so that the burner and parts thereof remain perfectly clean while in use. a

It is very desirable that effective means be provided for heating the burner initially to vaporize the fluid, and that this be done in such a way so as not to be objectionable to those using the burner, and also it is desirable that the same source of supply of fluid or oil for the burner be utilized tosupply the initial heating means. "As shown, Figs. 8 to 11, a device 71 is provided which has a part thereof located adjacent to the burner proper, and this device has a tubular part 7 2, the lower end of which is threaded and secured by a bushing 73 to the upper part of the tank so that air may pass within said tubular portion. The upper portion of the tube 72 may be bent so as to form an angle 7 at and has its upper end threaded. 'A valve casing 75 is secured to the upper end 74 andin said casing is a valve 76 which is adapted to control an opening 77 in said casing in the usual way. The valve is provided with an opening 78 which is adapted to be brought into communication with the opening 77 of the valve casing and with a chamber, as 79, at one side of the valve, and a larger chamber 80 at the other side of the valve within said casing, and said chamber 79 tapers toward the opening 77 and communicates with a plurality of openings 81 arranged in the end 74; of the tube 7 2. A small; tube, as 82, has one end held to the outer end of the tube 72, and said smaller tube extends within the tank and has its lower end open so that the oil, by reason of the air pressure above the same may be forced in a fine stream through said tube 82. A nozzle portion 83 is formed on the end of the tube 72 above the tube 82 for the-oil so that the effect of the air meetin the oil at the mouth of the nozzle 83 forms an atomizer causing the mixture in the form of a spray to pass through the opening 78 of the valve, through the chamber 82 and out through an opening 85 formed in the round-.

ed or substantially closed end 86 of the easing 75. The casing 75 may have an enlarged tubular member 87 secured thereto, as by the ribs or inwardly-projecting portions 88, and said member 87 is relatively larger than the casing 75 so'as to provide a chamber about the same in order that air may enter the lower open end 89 and commingle with the atomized spray to be ignited by means of a match or otherwise, a convenient means for lighting the spray being through an opening. 89 in the member 87. The lighted spray in the form of a heat flame will quickly heat the lower part of the cupshaped member 58 of the burner proper, and this Will cause the upper portion of the burner to be heated and also the heat to be transmitted to the lower portion of the same, so that the oil before passing to the opening 17 will be thoroughly vaporized.

By opening the cook 17, the air will escape from the reservoir and this will stop the flow of the oil to the burner or burners and to the atomizer, and this means mav be used with or independent of the valve 27.

It will be understood that while .the initial heating device, which is in the form of an atomizer, is a most effective means for initially heating the burner, other means may be employedif desired, and instead of a single atomizer or initial heating device on one side of the burner, there may be two, as 'shown in Fig. 12, or a number of them so arranged to heat the burner from opposite sides thereof. In this case the tube 72 has a branch 90 and within said branch is a small tube 91 which nection with a lamp or other lighting device.

As shown, a lamp 93 is mounted upon the stove to light .the room and out of the way of .the heating portion thereof, and said lamp has a burner substantially the same as that already described and similar to that shown at 71, the oil and air being supplied thereto as already described. Where the burner is used in connection with a lamp, a mantle 94 of the usual kind may be made to surround the burner or portion thereof, and said lamp may have a chimney as 95 with other attachments, as is usual with devices of this character.

From the foregoing it will be seen that simple and eificient means is provided whereby a burner may generate vapor from kerosene oil and unite with air supplied thereto to produce an effective heat flame; that said burner is simple in construction and may be readily made and assembled; that simple initial heating means is provided whereby the burner may be made to vaporize the oil; that said burner may be used for various purposes whether lighting 1 forming a chamber therebetween and connected to said burner, a cap fitting over said tubular member and having a plurality of openings therethrough, a plug resting on said cap and having a small.passage therethrough and forming a chamber underneath said plug above the ca and a rod a-djustable in said extension 0 the casing and having a handle at one end and a needle portion at the other end adapted to pass through the openingin the plug.
